` Be it knewn that I, ARTHUR KITSON, e subject of the Queen of Great: Britain, and a. resident of Philadelphia, (Germantowm) county. 5 of Philadelphia, Siete of Pennsylvania, have invented certain new and useful Improvemens yin Tlierniosmriealvee and Vapor- .inbee, of vwhich the following s a specifice-l tion,

My invention relates generally to vaporburning apparatus; and more specifically it consiste oi' an automatic valve constructed and leeeted te be operated thermosiziticelly in admitting, regulering, and @fitting 0E the supply of nil te theinperking-chamber of the ammi-nine; i

ln alie various forms of apparat-ne 'bn sning,Y *Jee ener oi' e iiiid' iiydzeoerbon snppiied under pressure considerable diicnlty line o 'neen experieneed inxLnerinesiei-ieallyregnleting the ndinission, supply", and cut olf of eil io'tne mpnriZing-ciminner. Suela dilienltvy arises mainly from failure to maintain the inlet closed until the temperature el' the Chamber nes been raised to the vaporizingpoin. Wnicli results in flooding ille chamber, @logging ille vapor-eimer, or discharging the nil upon the fnrnimre or contents of tlie reemin which ille lamp is being operated. 35e.

It is the objee oi' my invention, therefore, lo ebviaie the objections above eel fer-*li through the employment of n relire, selfelosinfr, to normally eut nii? all iiow vieil-- z'. under nimospiieric temperature-and which opens te admitl oil to the vziporizing- Chamber only when tile ienipemtnre of the saine has been raised to the point of vaporizatien or nenrly te said point'.

The preferred form of apparatus embodying my invention is illustrated by e View in sectional elerziaion inthe accompanying drawing.

The vaporizing tube 0r chamber l is 00nnected to the oii-snpply pipe 3 by means of a'threaded union 2 in the well-kno`wn way. The pipe 3,1eeding from the sorce of oilsupply, is controlled by any suitable form of valve 4 which is capable of accurate adjustment to prevent the discharge of eil under pressure er to permit the flow of the smile in requisite q uzuitisies. The end ofilie vaporzing-tube at Whieh i-lie oil is admit-ted is vpreferably mede in the form of e. eesiing,

having a valve-chamber `(3' and a valve-seat fel-ined therein for the cone-Vahle 7; also, a' Central bore extending ihroughoui iislengiah of a, dia-meter slightly in excess of alle valve- -etem 8, sc that when the vnlveis open the oil will be admitted ioshe tube in the form' of n thin film. the innerfaee of n screw-nap 5, which elose the open end of the casing, ennircles that port-ienl of the valve-Stena lyiner within the chamber b, sind serves in maintain Lhei'nlYe normally eiesed. v

Within tlievliody of ine veporizing-niie,

end preferably concentric Wit-li the exis there et', e iiierineaet rod nr filler l0 is xnnnnieii by being threaded it one end in s screw-ping l1, which latter is 'tapped inte and closes Ehe end of the mbe i, end et the opposiie end the rod 10 is looseiy entered in she bore 0f the casting 5 and is thereby lined with t-lie con-- tained vnlve-sienn'ihere being a. space or clearance between the Iadjoining ends of `tine rod and stem which may be varied ai; Will for n purpose Io be later on described. A jam or loeknut fen -lxe threaded end oi' the roll serves to secure Lne lat-ter in :my pesiiinn to which itmey be adjusted. The plug l?. is shouldered "ce nientngninst the end et' sliet'u'ee, ai which point iis dinmeier is enlarged te equal iiiesenie, and it is inreznied throughout its larger diameter for engzigeinenn with a oep 13. This een incluses une ensei' projeeing end o'f :lie thermostat; and is senken ed al-i to allow fer movement o the letter under adjustment..

.llo repreneurs the vapor-discharge opening in the lower side ofthe tube, and b' the npper end of-Llie mixing-tube, which is here ehevin in dotted lines relatively arranged to receive the jet; of vapor, as indientedl A spring-9, bearing agi-Linsen .i7 17 represent ganzes which niny ee insertedin the vaporizing-t-une and arranged eeneentrieally'abont to aid in @entering the thermostat-rod, 'as shown.

The outer wall of une easing of the reperburningv apparatus is indicated by the dotted lines 18 18, and with the tube relatively arranged as shown the lmain portion of the thermostat will lie within the casing in posi- -tion to be surrounded by the hot gases, 85e., in

their escape from the burner to the chimney.

It will' be observed that the ends of the tube are accessible, in that they lie outside of the casing -in an exposed position, and un'- der the cooling action of the air at atmospheric temperature both the spring-seated valve and the fixed end of the thermostat will bev more or less protected from the heat generated by the burner. This arrangement also serves to greatly facilitate adjustment or examination ot' either the valve or thermostat, in that it does not necessitate the removal of the tube from the casing.

The mode of operation of my invention is as'follows: With ihe vaporizing-tnbe in operative relationV to the iamp or other vaporburning apparatus the thermostatrod is adjusredand secured by the lock-nut to provide a space between its free'end and the adjoining end of the valve-stern. To effect the opening of thevalve, it is necessary that the thermostat-rod shall expand at a greater rate of speed than the tube, and at the same time it is also essential that the valve should remain closed until the temperature of the vaporizing-chambar has been raised sutilciently to eect vaporization of the oil when admitted. I secure the required diierence in the rate of expansion by constructing the vaporizing-tube of steel or an lequivalent metal and the thermostat-rod of brass, and regulate or retard the opening of the inletvalve by varying the space or clearance between the ,valve-stem and the end of the thermostat.- Normally, however, the valve is maintained `closed by its spring, and all access of oil to the vaporizing-chamber is thereby prevented. When the preheatiney of the vaporizing-tube is brought about in any one of the well-known ways-2', e., by the iiame 'of artrch or Bunsen burnerfor the purpose of starring the lamp into operation, the rod l0 will expand faster than lthe tube l, as above set fort-h, and in being secured at one end will advance under expansion in the direction of the Valve-stem. During the interval in which the rod isbeing lengthened by expansion to engage and operate the valve the temperature of the'vaporizing-chaniber will be brought up to the point required to eil'ectV the vaporization of the oil, and when the valve is finally movedfrom its 'seat in opposition to the spring the oil under pressure passes into the vaporizing-chamber in the form of a iilm, where it is converted into vapor and issues from the orifice l5 in the form of a jet. The vapor thus formed is burned in the vapor-burner in the well-known way, and the heat generated maintains the tube l at the necessary temperature for continued vaporization of the oil therein. As

long as this temperature isA maintained' the valve will remain open. If,however, thelamp goes 'out for any reason whatever, the thermostat will cool down rapidly, and' in contracting with greater rapidity than the tube will move away from the valve-stem and allow the spring to act and close the valve, thereby preventingfurther admission of oil to the chamber.

Some of the maina'dvantages of my Vinvention lie in the saving of oil by preventing waste thereof by defectivevalve mechanism; further,` in preventing iiooding of the vaporizing-chamber and escape of oil by effecting' a slow or retarded opening and a. quick closing of the inlet-valve; further, in the adaptability of the valve mechanism to vapor-tubes now in general use, and, finally, in thecon-l vcnience and facility with which the valve mechanism may be adjusted, examined,or repaired without removing the tube from the casing of the apparatus.

Itis evident, ofcourse, that variouschanges could be made in the details of construction illustrated without departing from the spirit and scope of my invention so long as the principle of operation described in the speciiicat-ion or the general relative arrangement of part-s' illustrated in the drawingl is pre served. Other forms of thermostat might be' employed and different forms of valve might be substituted. The thermostat might be differently located so long as it is within the heating'zone of the lamp-burner and ofthe. preheating device; g
